Why use Invisible poo bag when there are so many cheap alternatives?

Invisible poo bag is plastic-free, compostable, biodegradable and water-soluble, proven to be non-toxic and leaves no harmful residues on earth. Many cheap poo bags claim they are biodegradable but they contain plastic or polyester (PP, PE, PS, PVC, PLA) and form microplastic even when degraded. Plastic (including microplastics) takes hundreds of years to decompose in landfill.

Invisible poo bag is proven to be biodegradable in landfill anaerobic conditions and has been designed to be flushable in toilet, reducing the amount of toxic plastic in our landfills. Perfect for pet owners looking for an eco-friendly and convenient solution to dispose of their pet waste by replacing the conventional plastic bags or cheap "biodegradable" poo bags.


How do I dispose of my Invisible Poo Bag?

You can dispose it in pet waste bin or flush it in the toilet**.  Untie the poo bag and only flush 1 bag at a time. Invisible poo bag is truly biodegradable. Test result shows that in landfill (under high-solids anaerobic-digestion conditions), over 85% of the product degrades in 90 days. If you flush it, it will be treated at a sewage plant where, after being consumed by microorganisms, it will completely break down to only carbon dioxide and water.

**we do not recommend putting Invisible poo bag in toilet if your home is using a septic tank system (e.g. village houses)
